{"version":"1.0","type":"rich","title":"Making a smily face","description":"A yellow smiley face is drawn on an SVG canvas with two eyes, a smile, and animated eyebrows. The face is centered using a D3 selection with the `translate` transform, and the mouth is created with the `d3.arc` path generator. The eyebrows use `transition().duration()` to move up and down over two seconds each, demonstrating chained D3 transitions. The code relies on `d3.select`, `d3.arc`, and SVG elements like `circle` and `rect`, all rendered with d3.v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/43cce23d31054e179bdb6073f197c5bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
